ことを特徴とする速聞き機構付き音声再生装置。[Scope of Claim for Utility Model Registration] An audio playback section capable of high-speed playback of audio from a recording medium at a speed different from that during recording; sampling the playback signal played back at high speed by the audio playback section at predetermined time intervals; time axis expansion means that converts the frequency band of each sampled signal into the frequency band of the original signal and then connects and outputs the signal; and a signal near each connection point of the output signal from the time axis expansion means is muted. , a mute means for connecting the front and back of the muted part at a zero cross point, and a signal level of a part of the output signal from the mute means located before the mute connection part is gradually lowered, and the mute connection part 1. An audio reproduction device with a quick listening mechanism, characterized in that the audio reproduction device is equipped with a signal attenuator that gradually increases the signal level of a portion located later than the previous one.
